- gan, have' invented anew and Improved lVatenHeater7 ofvwhichthe followingis a specication.

This Ainvention relates-to means for heatf ing water andother liquids and` its object is to provide a water heatero'simplelconstructiom'that will bel very; compact, that can be constructed at'lowcost, and 4-that'will be efficient.

This invention consists in a horizontal -water chambery built' up of three substantially circular disks j oined ,together at their edges, the middle disk being-2 substantially flat andthe upper and low-er disksbeing bulged outwardly and preferablyconstituting spherical segments-the middlemember constituting adiaphragm lto-separa'te lthe v water chamber intov two divisions but-pro through'rthe lower head and connecting' into y an openingin the' diaphragm,I a seco-nd pipe to 'carry away the .water from ltheother.' division and extending down through "the upper head and connecting into another yopening'insaid diaphragui'r,V and a Yburner"linounted below the lowerhead..

insuch a=manner thatthehot ygases from theb'urner will be `forced topassaroundthe water V chamber in closeycontact with substantially Vthe entire surfaces of both theupsists in'means for preventingtlieupperand lower-heads ofthe water chamber from vseparating: more' than` predeterminedidistances rom the diaphragm. It Jfurther. consists in forming the housing inV two .parts normally, held together byixmeans oli/springs, v

which. `springs .permit the twok parts of- I the housingto separateV in case the pressure between=A them-v eXceeds arpredetermined aniountl yItfurthei' consists in fthe A'details of 'constructiom shownl in the drawingsand especially set forth.4 in the claims.

In the accompanyingfdrawings-Figure l is a central vertical-section of thisimp'rovedwater heater." Figs@ is -a-section oir-the line It y also consists in providing a shell or housingextending f' -around said water' chamber andsaid burner cured together 'in any desired manner, but

preferablyby rolling them onto each. other, asshowir in Fig, andthen unitingkby means of soldering, brazing orV welding.

vThetwo heads 3 `and 4f are bulged outwardly from thediaphragm 5 and preferably constitute-spherical segments. The lower head V4 is formed with.l a vcircularilange 6 at one side of the center into which the fleedfpipe 7 eXtend-s,whichpipe also extends-.up into the circular .flange S-onthe diaphragm 5. A discharge pipe 9 is lfastenedat its lower end within I'the circular yflangelO on thediaphragm -5 .and extends through the circular Yflange 121011 the head .3, f '.Ihese pipesff? and 9- are united to the iangesG, 8,' 10 and l2 byf soldering, brazing. or welding in order that the jointsmayjbe absolutely-tight. 'Ihe discharge pipe 9 is preferably mounted. centrallyof the waterk chambverrandl directly over the burner.

Any desired-means may lie-employed to prevent the heads 3 and 4f from -beingvi'orcedA too zfar apart by high pressures within the.

water chamber.' In Fig-.1, a rod l/is shownprovidedi'with afoot 16 united to the head 4in any'd'esired manner; The=upper end oftherod :l5 is formed with` an feye'f-l' vthrough which and :the wal-ls of thefpipe 9 i the pin- 18 extends; per and thelowerheads.: It-furtherfcon Surround-ing the water chamber -is af/vhous-V l ing, preferably offcastiron, formed of the upper part' 19 of thehousing areshown Yresting von .theupperl head T3 of the w-at'erichain-v` ber. y Lateral'movement between the housing .and water chamber'will be prevented by the pipes 7 and -9. Theburnt gasesfmay'be carried of by means oan elbow-24 connected tothe middle-ofA theupper partvl9 of the housing. Studs 25 are shown screwed into the lowerI part 2O of the housing and extend up through holes in the upper part. Nuts 26 and springsV 27 on these studs hold these two parts of the housing firmly together, but should an explosion occur within the housing, these springs 27 will yield and permit the two parts of the housing to separate and the pressure to be relieved.

T he burner shown in the drawing is only an example of what may be employed. Any other desired means may be used to apply heat to this water chamber. ln the drawing the body 29 of an ordinary Bunsen burner extends up through a hole in the combustion chamber and the head or ring 32 is connected to the upper end of this body. A. perforated disk 33 of any desired character may be secured in this head or rino' for the purpose of causing the mixed gas and air to flow evenly from the burner. Gas may be supplied by means of a pipe 3l. Because of the location of this burner immediately below the intake end of the discharge pipe 9, the water passing up into this pipe will be of maximum temperature. if desired, a nut 34 may be used to secure the burner in position.

As the water passes through the pipe 7 to the upper division of the water chamber and is there warmed before it enters the vlower division, the head l will not be lrept cold and condensation of the water vapor resulting from combustion will be avoided. As the pipe 9 is directly above the burner, the hottest water will always be ust at the inlet of this pipe. rlhe curvature of the housing is such that the hot gases and flames will be directly in engagement with all of the outer surfaces of the water chamber and maximum efliciency is attained.

I claim l. n a water heater, the combination of a water chamber consisting of upper and lower outwardly convex heads and a substantially flat horizontal diaphragm between them, a pipe connecting into the space above the diaphragm to supply water thereto, said diaphragm having a hole through which said water may pass to the space below it, a burner below the lower head, and a housing extending around the burner and then around the water chamber with its walls substantially parallel to the outer portion of the lower head and to the upper head to cause the burnt gases to flow in engagement with said surfaces of the water chamber.
